Hey guys im upgrading from my 48x24x24 back to a cube 36x36x24(130g). I currently have 1 radion gen 2 but was thinking I might need another for the cube but wasnt sure. What do ya think?

No need the spectrum of radion is 30*30 inch raise it little bit up more than 10"
How it was working for ur old tank ?

I had it on a 24x24x24 cube and it was amazing, I then purchased the 48x24x24 and I need 2 for full coverage, dark spots appear 4 inches inn on each side of the tank. Since I probably dont need another light for this cube I can get a mp40 instead. thanks for the help
